Small Size Graphite Heater
Compact graphite resistance heating element for small-chamber vacuum furnaces, laboratory sintering units and desktop heat treatment equipment. Precision-machined to ±0.01 mm. Operating temperature to 2200°C.
Small-format graphite heating elements precision-machined from isostatic graphite for compact vacuum furnaces, laboratory tube furnaces, desktop sintering units and research equipment. Tight dimensional tolerances (±0.01 mm) are maintained for precise fit within compact hot zone assemblies where clearances are critical. Available in miniature rod, split-ring and custom geometries. Resistance values verified individually prior to shipment to ensure predictable electrical performance in low-power systems.
